How come there's Greek text on this image ;o

I scanned the QR code and this is what it says:
https://www.ki7ko.com/datenshi

There's more greek text in the page:
"
ギリシャ語
Δεν ξέρω το όνομά μου.
Lucifer και φίλοι.
Μου αρέσει να κάνω κακό στους ανθρώπους
Μου αρέσει επίσης να καπνίζω.
Αλλά σχεδόν πάντα κοιμάμαι
"

With Google Translate it says:
"
Greek language
I do not know my name.
Lucifer and friends.
I like to hurt people
I also like to smoke.
But I almost always sleep
"

It also reports the same phrases in Japanese.

Yeah i know what it says, i'm Greek :) That google translation is pretty accurate i'd say.

At least it makes some sense, i've seen sometimes japanese companies use Greek letters/phrases in games/manga/anime that amount to gibberish in Greek lol
